feat(client): Make opacity and shadows of build placement preview objects customizable

[xezon]

• Merge after fix(shadow): Fix initial shadow states of draw modules #1591

This change makes the opacity and shadows of build placement preview objects customizable. It adds new fields ObjectPlacementOpacity=0..1 and ObjectPlacementShadows=Yes/No to GameData.ini.

By default, user facing nothing changes.

I put the mod fields into GameData.ini instead of InGameUI.ini because thematically it does not fit in InGameUI, despite being referenced there.

I have chosen the new fields names because there is precedent in Object: PlacementViewAngle.

Example Modification

ObjectPlacementOpacity = 0.60
ObjectPlacementShadows = No
